How to Do Lying Knee Raise

  1. 1
    Setup

    Lie flat on your back on a mat, with your arms extended alongside your body, palms down, or hands tucked lightly under your glutes for lower back support.

  2. 2
    Setup

    Keep your legs extended straight, heels hovering just an inch or two off the floor, or with a slight bend in the knees if your lower back feels strained.

  3. 3

    Exhale as you slowly draw both knees towards your chest, simultaneously lifting your hips slightly off the floor by engaging your lower abdominal muscles.

  4. 4

    Continue until your knees are directly over your hips, or as close to your chest as comfort allows, ensuring your lower back remains pressed into the mat.

  5. 5

    Inhale as you slowly and with control extend your legs back to the starting position, maintaining tension in your core and preventing your heels from touching the floor.

Tips

  • Focus on pressing your lower back into the mat throughout the movement to maximize core engagement and protect your spine.
  • Control the lowering phase of the movement; don't let gravity just drop your legs, as this eccentric control is crucial for building core strength.
  • Initiate the movement by tilting your pelvis and lifting your hips slightly off the floor, rather than just bending your knees, to properly engage the lower abs.
  • Breathe out as you raise your knees and inhale as you lower them; this helps engage your core more effectively and stabilize your trunk.

Common Mistakes

  • ×Arching the lower back during the movement can lead to spinal discomfort; keep your lower back pressed into the mat to prevent strain and ensure proper abdominal engagement.
  • ×Using momentum to swing your legs up reduces muscle activation; perform the movement slowly and controlled, focusing on a deliberate muscle contraction.
  • ×Letting your heels touch the floor at the bottom of the movement releases tension; maintain constant tension in your core by keeping your heels hovering just above the floor.
